How I architect full-stack systems
Product Architecture
Define user flows, feature requirements, database schema, and API contracts before development begins.
Frontend Foundation
Next.js App Router with Server Components for performance, responsive Tailwind layouts, and accessible UI components.
Backend & Data
RESTful APIs with NestJS or Express, PostgreSQL/MongoDB schemas, auth middleware, and payment webhook handling.
Integration & Polish
Connect frontend to API, add real-time features, optimize Core Web Vitals, and implement error boundaries.
Deploy & Scale
Containerized deployment, CDN configuration, monitoring, and performance optimization for production traffic.
Featured Work
Production projects as a Full-Stack engineer
DispatchLink
B2B Freight Marketplace Connecting Carriers & Dispatchers
Problem
Freight dispatching is plagued by manual phone calls, untracked load confirmations, fragmented broker commissions, and slow escrow reconciliation.
Solution
Architected a unified real-time portal where carriers claim loads with automated geospatial radius search, live driver telemetry, and automated multi-tenant wallet payouts.
Architecture
- Next.js 15 App Router with Server Components for low-latency freight searches
- MongoDB 2dsphere indexes for polygon and radius origin-to-destination matching
- MapLibre vector maps rendering live driver routes and telemetry coordinates
- LemonSqueezy merchant-of-record integration for multi-party escrow billing

SchedMate
Enterprise Workforce Management & Shift Dispatching Platform
Problem
Enterprise facilities with hundreds of nurses and field contractors faced scheduling collisions, missed shifts, and manual attendance calculation across distributed branches.
Solution
Engineered decoupled NestJS microservices backed by Kafka event streams, Redis BullMQ background workers, and strictly typed PostgreSQL schemas.
Architecture
- NestJS modular microservices architecture partitioned by domain context
- Kafka distributed event streaming to synchronize shift allocations in real time
- Redis BullMQ worker queues handling scheduled shift notifications and reminders
- PostgreSQL + Prisma ORM with transactional safety and row-level audit trails
Verified Results
Trace3D
No-Code In-Browser WebAR & 3D Spatial Rendering Engine
Problem
Traditional augmented reality requires users to download heavy mobile applications from the App Store, creating an 80%+ drop-off barrier for commercial brands.
Solution
Leveraged WebXR, Three.js, and WebGL to deliver photorealistic instant 3D model projection with zero app installations, triggered by simple QR codes and mobile browser links.
Architecture
- Three.js & WebXR render loop delivering smooth 60 FPS surface-tracking projection
- Client-side Draco mesh compression reducing 3D file payloads by over 70%
- CloudFront CDN and AWS S3 storage for instantaneous asset hydration
- Dynamic material and texture swapping interface built with React & TypeScript
Verified Results

FAQ
Frequently asked questions
Do you build entire SaaS products from scratch?
Yes. I've founded and shipped production SaaS platforms like DispatchLink (B2B freight marketplace) from database design to deployment. I own the complete vertical — frontend, backend, auth, payments, DevOps.
What's your frontend tech stack?
Next.js 15/16 with App Router and Server Components, React 19, TypeScript, and Tailwind CSS. I build responsive, accessible interfaces with strong Core Web Vitals performance.
Can you work on an existing codebase?
Absolutely. I audit existing code, identify performance bottlenecks, refactor architecture where needed, and add new features without breaking existing functionality.
Do you handle payments and auth?
Yes — I integrate LemonSqueezy and Stripe for payment processing, webhooks, and multi-party escrow. For auth, I implement JWT, OAuth, and role-based access control.
Need a complete SaaS platform built?
From UI to API to deployment — I own the entire stack and ship production products.
